So. to write compatible scripts one should check "< 0", not "== -1".
Which matches the documentation:
Returns < 0 if str1 is less than str2; > 0 if str1 is greater than str2,
and 0 if they are equal.
I think the point here is that the documentation says the function
returns a number greater than zero, or less than zero, or zero.
It's just that many who have responded on this list show that the
function commonly returns -1, 1, and 0.
It's wise to keep with the documentation.
